Interview Process

The interview began with a basic introduction about my background and experiences. Then, I was presented with the Rate Limiter question, where I was asked to implement a rate limiter that allows a certain number of requests per second. The interviewer followed up with questions regarding edge cases and optimizations. I explained my approach using a sliding window algorithm. After discussing the initial implementation, I was asked to analyze the time and space complexity. We finished by discussing system design considerations for handling different traffic patterns effectively.
